EXCLUSIVE: Mila Kunis Says She and Ashton Kutcher Are 'Good' With 2 Kids, Describes Their 'Crazy' Home Life

At CinemaCon in Las Vegas on Tuesday, ET spoke with the 33-year-old actress, who's gearing up to start shooting Bad Mom's Christmas -- the sequel to last year's hit, Bad Moms -- next month. Kunis gave birth to her and husband Ashton Kutcher's second child together, son Dimitri, in late November, and revealed that the A-list couple isn't jonesing for a third child any time soon!

"[With two kids] you're running defense a little bit, like, one's got one and the other's got one and it's OK," she added. "I think it's when it becomes three is when you're like, you're just playing offense. I don't know what you do at that point. You're scrambling trying to keep them all in line."

Still, Kunis admitted her and Kutcher's home has already been completely taken over by their 2-year-old daughter, Wyatt, and baby Dimitri!

"We feel like we're being suffocated by plastic with toys and diapers and things," she said. "It's crazy."

"We used to be cool and clean," she joked. "It's like, our house used to be nice and modern and pristine -- all goes out the window when you got kids."

Kunis said she's definitely more relaxed this time around with baby number two, and that she's feeling "great" almost four months after giving birth. The beautiful brunette stunned at the event in a simple black top and wide-leg trousers, which she paired with black-and-white heels.

"He's awesome," she gushed about her newborn son. "Baby one to two is different. Baby one, I would've been like, 'OMG, OMG, what am I gonna do?' Baby two I'm like, 'I got my pump bag, I got my clock going, I gotta be picking up from school in, like, three hours. I gotta go.' You're a little bit more on a time schedule."

"The first one I was weeping," she admitted. "This one, I'm like, 'It's fine. Everyone's alive, it's all good.'"

It turns out being shy about certain things also goes out the window.

"I mean, people are like, 'Do you need a private room to pump?' and I was like, 'Nope, no, I'll do it right there,'" she said. "I don't care. Like, literally, I just don't. It's so different."

"My wife came to this country on a refugee visa in the middle of the Cold War!" he tweeted. "My blood is boiling right now! We have never been a nation built on fear. Compassion that is the root ethic of America. Our differences are fundamental 2R sustainability."
